Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.02260 | $0.02260 |
| Opus 5 | $0.01130 | $0.01130 |
| Sonnet 5 | $0.00452 | $0.00452 |
| Haiku 4.5 | $0.00226 | $0.00226 |
Grade A, and why
codex-desktop-linux AGENTS.md scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Purpose
This repository adapts the official macOS Codex Desktop DMG into a runnable
Linux app, packages it as .deb, .rpm, pacman, and AppImage artifacts, and
ships a local Rust update manager that can rebuild future Linux packages from
newer upstream DMGs.
The build flow: install.sh downloads/extracts Codex.dmg, patches the
extracted app through core and enabled Linux feature descriptors, rebuilds
native modules, downloads Linux Electron, stages bundled resources, writes
codex-app/start.sh, and lets package builders produce native artifacts or
AppImage. Native packages also include codex-update-manager and an
update-builder bundle.
Maintainer Rules
- This project supports only the latest upstream
CODEX.DMG. When fixing upstream drift, remove old drift workarounds in the same change. Do not keep legacy DMG shapes, fallback patch paths, or version-specific compatibility branches around. - Keep core behavior focused on the app launching and working for most Linux
users. Experimental, workflow-specific, editor-specific, browser-specific,
distro-specific, or minority-use integrations belong in
linux-features/and must be disabled by default. - If an optional feature needs a new core touchpoint, add the smallest generic extension point to core, then keep feature-specific logic inside that feature directory.
- Do not enable optional features in committed config.
linux-features/features.jsonis local and gitignored;features.example.jsonstays empty. - Each repository feature under
linux-features/<id>/and each local feature underlinux-features/local/<id>/must include aREADME.mdnext tofeature.json. - Do not manually patch generated output such as
codex-app/start.shfor a durable fix. Change the source template, build helper, feature, or patch descriptor and regenerate. - Treat updater, package builder, launcher, and feature framework changes as cross-format changes unless the code explicitly scopes them to one package format or desktop target.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

codex-desktop-linux AGENTS.md is an instructions file published in the GitHub repository distsystem/codex-desktop-linux (11 stars, last pushed 1mo ago), licensed MIT. It adds 2,260 tokens to every session, about $0.0113 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
